سنن أبي داود#13Hasanحَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا وَهْبُ بْنُ جَرِيرٍ، حَدَّثَنَا أَبِي قَالَ، سَمِعْتُ مُحَمَّدَ بْنَ إِسْحَاقَ، يُحَدِّثُ عَنْ أَبَانَ بْنِ صَالِحٍ، عَنْ مُجَاهِدٍ، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، قَالَ نَهَى نَبِيُّ اللَّهِ صلى الله عليه وسلم أَنْ نَسْتَقْبِلَ الْقِبْلَةَ بِبَوْلٍ فَرَأَيْتُهُ قَبْلَ أَنْ يُقْبَضَ بِعَامٍ يَسْتَقْبِلُهَا .
Narrated Jabir ibn Abdullah: The Prophet of Allah (ﷺ) forbade us to face the qiblah at the time of making water. Then I saw him facing it (qiblah) urinating or easing himself one year before his death
